“…Nevertheless, overall, their growth was better than that of Cynodon dactylon grown in plain soil. erefore, nutrients in the substrate can promote the growth of plants, which is also consistent with the research of Ray Sarkar et al [11].…”

“…Many researchers have found that the addition of fly ash to soil is beneficial to plant growth, and soil improvements fly ash that is full of phosphorus, potassium, and calcium will trigger a series of biological reactions when mixed with soil. Bierman and Rosen [10], Ray Sarkar et al [11], and Singh et al [12] have found that fly ash added into the soil can increase essential plant elements, such as N, P, K, and Si, which promote plant growth. Wang et al have found that it is feasible to use fly ash to improve acid soil [13].…”

In order to realize the resource utilization of fly ash, a kind of ecological slope protection substrate was prepared by mixing fly ash produced by MSW incineration into slope protection soil. Through the direct shear test and a leaching experiment on ion pollutants, the influence that shear strength of the substrate changed with root content, ash content, and moisture content and the ecological effects of leach liquor were investigated. The results showed the following: (1) When the optimum moisture content is about 24.9%, the shear strength of the substrate is the maximum. (2) Fly ash can improve the shear strength of the soil, which can reach 1.67 times as much as that of plain soil, and the optimum content of fly ash is 5%–6.7%. (3) The root system can increase the cohesion and internal friction angle of the substrate soil but mainly increases the cohesion of the substrate soil. (4) Plants grow taller in ash-mixed soil than in plain soil. (5) When the fly ash content is 20%, the ion concentrations of Cl, Cu, and Zn are the highest: 220.7, 0.153, and 1.526 mg/L, respectively. All of them are lower than the standard limit of class V water and gradually decrease with time. Therefore, the leaching liquid will not cause environmental pollution and meet the ecological requirements.

“…Strains were grown under a standard Fe condition, and cultures with an optical density of 0.7–0.8 were pelleted down and resuspended in the buffer. Then, 100 µL of the sample was removed from the provided sample vials 44 , 45 , and mixed with 9.9 mL of miliQ water to prepare a 100 times dilution of the sample. Next, these diluted samples were analyzed through ICP-MS; during the analysis, 3 mL of the 10-mL sample was consumed by sample injector channels.…”

Iron homeostasis in Mycobacterium tuberculosis is essential for persistence

Tuberculosis, caused by the obligate intracellular pathogen Mycobacterium tuberculosis (Mtb), is responsible for 2–3 million deaths annually worldwide. Intracellular adaptability, which is critical for long-term persistence, requires the pathogen to neutralize host-mediated insults. The iron–sulphur (Fe–S) cofactor is essential for many enzymes critical for such ‘adaptation’. The Mtb genome harbors only one putative iron–sulphur cluster (ISC) operon (rv1460-66) predicted to be involved in the generation of the Fe–S cofactor. Except for rv1460, all other genes in this operon are anticipated to be essential. The current study investigated the role of rv1460, an sufR homologue of Mtb (sufRTB), in maintaining intracellular Fe homeostasis and its implications on mycobacterial pathogenesis. We found that Mtb ISC locus (rv1461–66) was transcribed as a single multigene transcript. We successfully generated the sufRTB null mutant strain (ΔsufRTB) of Mtb, suggesting nonessentiality of the gene under normal growth conditions. The mutant strain demonstrated enhanced biofilm generation and failed to grow under a low-Fe condition. Growth characterization studies indicated that SufRTB-mediated intracellular Fe homeostasis is essential for Mtb to persist in the host. Targeting mycobacterial persistence by inhibiting SufRTB protein activity may be a novel intervention strategy in tuberculosis treatment.

“…The results have further shown that all Typha species have the same concentrations of elements in their roots, rhizomes and leaves, while the mobility of similar elements flows from the sediments to roots and roots to leaves. Yet another study on Typha latifolia plants in wetlands has also been performed by [17], which discussed fly ash mixed with soil in four different proportions of 0% (FA0), 25% (FA25), 50% (FA50), and 75% (FA75). Meanwhile, an investigation on the pyrolysis of Typha latifolia has been investigated in [18], which utilised various mixtures of T. latifolia, T. Angustifolia, and T. glauca.…”

Research on the ability of plants to reduce and transport pollutants, especially heavy metals, remain advancing to date in line with current technological developments. The purpose of this study was to investigate the effect of leachate concentration on the number of tillers of Typha latifolia plants. It also investigated the leaf length and number of leaf petals of these plants. The materials used in this study included liquid/leachate media sourced from a landfill in Banda Aceh, the aquatic plants of Typha latifolia (torch), and heavy metals such as chromium (Cr), mercury (Hg), and lead (Pb). The results showed that the increase in Typha latifolia plant roots occurred at leachate concentration of 20%, 40%, and 60% for sources of 4 cm, 2 cm, and 1 cm. Meanwhile, the leaf length was observed in the leachate concentrations of 20%, 40%, and 60%, resulting in enhancers of 6 cm, 1 cm and 1 cm. Besides, increments of leaf number occurred at leachate concentrations of 20% and 40%, yielding as much as 1 and one leaves on the 2nd and 4th week. The overall results of the study showed an increase in low concentrations.
